Numerical simulations showing the spatial structure of the dynamo magnetic field generated for a fluid astrophysical object. The colored sphere indicates the amplitude of the radial magnetic field at the surface of the core-mantle boundary. The lines indicate the magnetic field in the insulating mantle and outside of the astrophysical object.
